"Unfortunately, a number of roads will be closed to traffic for short periods whilst the runners pass-by. We have worked very closely with the Police, Highways and the local council to minimise disruption and there are diversion plans in place to ensure people can still get around town."

Several charities have got runners taking part to raise money for them. Dawn Wright is from local group The Lowdown - which supports young people between the ages of 12 and 25. She is really pleased with the support they're getting:

"We've got 45 people taking part which is loads! Because it's our 21st year we'd hoped to get at least 21 people. And to have more than doubled that, we're really chuffed."

"Because all of our fundraising campaign this year has been 21 themed, we hoped that they would raise at least £2,100 - and we hope that they can achieve that and hopefully pass it."
